Remove unused parameter from two TUI functions

The "display_prompt" parameter of tui_erase_source_content and
tui_clear_source_content was never passed the NO_EMPTY_SOURCE_PROMPT
value, so remove the parameter.  Once this is done, the
EMPTY_SOURCE_PROMPT and NO_EMPTY_SOURCE_PROMPT defines are unused, so
remove those as well.
