Fix #110341: Appended text looses user after reload

Browse source 
Even if a text datablock was "used" by in the Text Editor, it would be
lost after save/reload if no fake user is set.

This is not in line with other datablocks if they are used by an editor
(e.g. images, clips, masks etc.).

Now handle this with `IDWALK_CB_USER_ONE` (instead of `IDWALK_CB_NOP`)
in `id_refcount_recompute_callback` >
`BKE_screen_foreach_id_screen_area` which re-ensures a user is set.

(Bit on shaky ground here, but this seems like this is how this is
handled for other editors "consuming" a datablock).
