Make sure we don't call back into GtkEntryBuffer

Browse Source 
After commit 7e77afe94c moved the deletion
of text into the signal handler, in order to make undo work, we need to
override the GtkEntryBuffer::deleted-text class closure when subclassing
GtkEntryBuffer, as well as overriding GtkEntryBufferClass.delete_text,
otherwise the default class closure will be invoked, and will try to
delete an empty buffer.

Fixes: #3140
