fixes#47101
The bug was introduced in #33495, where `spack find was not updated,
and wasn't caught by unit tests.
Now a Database can accept a custom predicate to select the installation
records. A unit test is added to prevent regressions. The weird convention
of having `any` as a default value has been replaced by the more commonly
used `None`.
