fix(database): Handle String errors in DatabaseModal

[Antonio-RiveroMartnez]

SUMMARY

At some point we stopped handling and displaying API errors coming as raw strings in the DatabaseModal. We are bringing that back, so for example, if someone tries to connect a BigQuery DB using credential JSON files with no roles in it, an error gets displayed vs no indication at all.
