Use _dbs_info instead of fetching the db info one-by-one

Overview

Slight efficiency improvement, use _dbs_info instead of fetching the info about the databases one by one.

Note, I'm by no means a react expert, so please let me know if I missed something or otherwise did something stupid.

Testing recommendations

Visit the all dbs page. It should work the same.
