Selecting quick fixes does not cause linting errors to go away automatically unless connected to MATLAB

[dklilley]

Is your feature request related to a problem? Please describe.
When selecting the quick fix to resolve a mismatch between the name of my custom MATLAB and the .m file that it is written in, the linting error for the function name does not get resolved unless I manually save the file (when MATLAB is not connected).

Without manually saving the .m file, the extension allows me to select the same quick fix multiple times which can lead to unexpected behavior.

Describe the solution you'd like
The diagnostic message should disappear when the quick fix is applied.
