Switching connections doesnt work due to AuthCache

[matthewjumpsoffbuildings]

If I have 2 different spanner connections setup in my config/databases.php, with different project IDs and key files, if I connect to one via DB::connection('spanner-one'), do some queries, then try and connect to the other with DB::connection('spanner-two'), it fails, with IAM permission denied errors.

It appears the auth from the first connection, which is now cached in storage/framework/spanner/_auth, is being loaded via the AuthCache into the second connection, and of course doesnt have the necessary permissions since the second connection should use an entirely different project/key file/auth

If however, I query the first connection, manually delete the storage/framework/spanner/ folder, then query the second one, it does work as expected.

I tried using spanner:cooldown on the first connection before attempting to use the second, but this didnt work, it doesnt appear to clear the storage/framework/spanner/_auth folder
