Make Text Selection Action Mode secondary items IF_ROOM

The fact that they were all ALWAYS caused the ActionBar version
of the ActionMode to show truncated text to try and fit them all.

In an ideal case we will always have a Floating ActionMode, but
the client can explicitely change this and hence we should fallback
gracefully.

Additionally, remove the SHOW_AS_ACTION_WITH_TEXT flags as we
removed the icons from the items anyway.
