New tests added later for the incoming "with" command exposed a couple
invalid-default-value bugs in the "maint test-settings" commands:

- var_filename commands don't allow setting the filename to the empty
  string (unlike var_optional_filename commands), yet, "maint
  test-settings filename"'s control variable was not initialized, so
  on startup, "maint test-settings show filename" shows an empty
  string.

- "maint test-settings enum"'s control variable was not initialized,
  so on startup, "maint test-settings show enum" shows an empty value
  instead of a valid enum value.

Both issues are fixed by initializing the control variables.
