bplapply() et al. returns RngFutureError:s rather than signals them

[HenrikBengtsson]

library(BiocParallel.FutureParam)
register(FutureParam())
options(future.rng.onMisuse = "error")
y <- bplapply(1:2, rnorm)

> str(y)

The expected behavior should be:

y <- bplapply(1:2, rnorm)
Error: UNRELIABLE VALUE: Future ('<none>') unexpectedly generated random numbers without specifying argument 'seed'. There is a risk that those random numbers are not statistically sound and the overall results might be invalid. To fix this, specify 'seed=TRUE'. This ensures that proper, parallel-safe random numbers are produced via the L'Ecuyer-CMRG method. To disable this check, use 'seed=NULL', or set option 'future.rng.onMisuse' to "ignore".

Similarly, with RngFutureWarning:s, we would expect:

library(BiocParallel.FutureParam)
register(FutureParam())
options(future.rng.onMisuse = "warning")  # default
y <- bplapply(1:2, rnorm)
Warning: UNRELIABLE VALUE: Future ('<none>') unexpectedly generated random numbers without specifying argument 'seed'. There is a risk that those random numbers are not statistically sound and the overall results might be invalid. To fix this, specify 'seed=TRUE'. This ensures that proper, parallel-safe random numbers are produced via the L'Ecuyer-CMRG method. To disable this check, use 'seed=NULL', or set option 'future.rng.onMisuse' to "ignore".

but right now those warnings are muffled and never signaled.
