Issue description

I was fixing the warnings and wasing really paying attention to what the [ignore] link was doing and ended up with a dozen copies of "# warning-ignore:return_value_discarded" inserted into my files as it's not detecting them.

Steps to reproduce

Open the attached new_script.gd in the built-in editor. Open the warning panel. Click on the [Ignore] on

"[Ignore]Line 6 (RETURN_VALUE_DISCARDED):The function 'connect()' returns a value, but this value is never used."
or "[Ignore]Line 8 (RETURN_VALUE_DISCARDED):The function 'connect()' returns a value, but this value is never used."

I suppose clicking the Ignore button should remove the line in question from the warnings list automatically, without waiting for the script editor to parse the script again.

It does reparse the script and reports it one line later, now that it's added ignore line.
