Revert "sddm: Fix test."

This reverts commit 0a6a0634

.

The commit replaced the text to search for from ALICE to BOB, because
our OCR detection only caught "BOB FOOBAR" but missed "ALICE FOOBAR"
completely.

With the improvements to our OCR system this no longer is the case and
the test passes successfully with this reverted.
