gp2tbl function produces too much output

[mverouden]

I have updated the documentation of ba_germplasm_details and fixed some coding inaccuracies (resp instead of res, cont instead of res2).

Upon testing the call with:
on <- ba_db()$testserver
ba_germplasm_details(con, germplasmDbId = "1")

Much duplicated output appears. This needs to be fixed in gp2tbl()

There is a line for each distinct entry in the fields/columns that may have multiple lines as in donors.accesionNumber or taxonId. Intended. Should we change? Has implications to streamline other calls.
