Don't checkDimnames when making SummarizedExperiment

[jamespeapen]

We've been getting this error when using bsseq::combine on bsseq objects with different colnames:

Error in SummarizedExperiment(assays = ans_assays,rowRanges = ans_rowRanges,: 
the rownames and colnames of the supplied assay(s) must be NULL or 
identical to those of the RangedSummarizedExperiment object (or derivative) to construct

This patch remvoves the validity check so that the SummarizedExperiment object is created without error.

@jamespeapen can you please share a reprex that illustrates the problem.

bs_list <- readRDS("bslist.rds")
myBS <- bs_list[[1]]
for (i in (2:length(bs_list))) {
  myBS <- bsseq::combine(myBS, bs_list[[i]])
}

Sorry, I've been very busy and haven't had time to consider this, yet.
@kasperdanielhansen what do you think?
