nixos/tests/signal-desktop: Improve the DB test

Browse source 
The command "file ~/.config/Signal/sql/db.sqlite | grep 'db.sqlite: data'"
can randomly fail because "file" sometimes recognizes the "random"
(encrypted) data as something. This occasionally causes test failures,
e.g. [0] were it was recognized as "PGP Secret Sub-key -" or in another
instance as an ext4 filesystem [1].
