sw content controls: fixes for the ending dummy char

- make sure the DOC/RTF export doesn't write the dummy char as-is

- let "enter" only insert a linebreak while inside a content control, to
ensure that the starting and ending dummy char stays inside the same
text node

- let deletion of the dummy character at the end behave the same as the
start dummy character: if trying to delete that single character, then
just move the cursor, don't delete it

- reject document insertion in the middle of a content control, similar
to input fields
