TEI group element seems to confuse HookTest on Travis CI #105
Description
My files in the cts-croala repository pass the local hooktest validation without errors. However, when trying to build with Travis CI, HookTest has problems with documents which contain a TEI group element. For example:
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| Identifier | Words | Nodes | Failed Tests |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| baric01.croala1506566.croala-lat1.xml | 2,020 | 2;11;9;12;41;107 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| levak01.croala2069172.croala-lat1.xml | 6,573 | 1;11;22;22;111;156;59 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| marul01.croala754085.croala-lat1.xml | 14,379 | 2;13;25;24;184;1632;914 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| skrl01.croala1410547.croala-lat1.xml | 68,595 | 1;5;11;205;310;680;1121;1368 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| skrl01.croala1676802.croala-lat1.xml | 71,071 | 1;4;8;208;816;3085;1345;78;44 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| skrl01.croala735015.croala-lat1.xml | 12,796 | 3;18;24;237;288;28;12 | Correct xml:lang attribute |
+---------------------------------------+--------+-------------------------------------+-----------------------------+
| skrl01.croala940507.croala-lat1.xml | 44,852 | 1;13;10;76;342;1130;1730;322;225;26 | Correct xml:lang attribute |

group is a useful solution for texts consisting of other texts. It would be good that hooktest takes it into account when testing tei files. The structure is:
