(fix): refactor error handling using ignore-errors

(condition-case nil
    (test)
  (t nil))

Is a construct that's only available starting from Emacs 27. Since
Org-roam supports Emacs 26, gotta use what's given.

Note: ignore-errors isn't exactly the same as the construct above from
Emacs 27. Compare to ignore-errors to would trap all possible signals,
while ignore-errors will only trap "error" signals. This, however,
shouldn't affect us in case of this refactoring.

Fixes #1777.
