Changing passphrase of Persistent Storage reports an error even if it eventually succeeds after the frontend stopped waiting for it

From wb:7052d016b3824a8af9d43e2ce295fc9, I understand the frontend times out after waiting ~30s, while the operation succeeds in the backend after ~45s:

Any reason why we should not switch to timeout_msec=GLib.MAXINT, that the frontend uses for activation/deactivation of features, and deletion/creation of Persistent Storage?

Alternatively, I suppose that bumping the timeout to 1 min should work most of the time.
