Fix similarity frequency 500 errors

[johnbradley]

When running the tests locally the following 500 errors occur:

[ FAIL 2 | WARN 0 | SKIP 0 | PASS 640 ]

One of the errors can be also seen by running the following code:

phens <- get_phenotypes("basihyal bone", taxon = "Cyprinidae")
subs.mat <- subsumer_matrix(phens$id, .colnames = "label", .labels = phens$label, preserveOrder = TRUE)
> sm.ic <- resnik_similarity(subs.mat, wt_args = list(as = "phenotype", corpus = "taxon-variation"))
Error in get_csv_data(pkb_api("/similarity/frequency"), query = query,  : 
  (500) Internal Server Error: There was an internal server error.

This error does not occur during the CircleCI tests because of the skip_on_cran() function.

@balhoff fixed this by increasing Qlever resources in the phenoscape KB API service.
