Per https://forum.kee.pm/t/edge-89-0-774-50-official-build-64-bit-kee-3-7-8-does-not-start/3572/ one possible explanation for this is that there is no valid home group set in one of the databases.

Some better handling of this error state in jsonrpcClient.ts:getAllDatabases() could:

1. Offer some better console log feedback within the browser (rather than having to look at KeePass)
2. Ensu

When a user would like to use yarn, it needs to be installed, even when --skip-install option is used.
I think this check could be moved to the actual install phase, simply throwing a warning like "Yarn is not installed, skipping install. Please install yarn on your machine." is enough.
