fix indentation of current-line (=) stopped working

Previously, I was able to do fix-indentation with == in vscode with vim plugin.
This stopped working with latest vscode upgrade.

To Reproduce

• Open code in any programming language and go to any line that is not indented correctly.
• Press == to indent it. Nothing happens.

python_var = some_python_function(arg_a, arg_b, arg_c,
         arg_d)        #  == on this line should fix the indentation.

Expected behavior
Please see above.

Reproduce the failure in VSCodeVim v1.25.2 by opening a misindented file and pressing ==, then compare the keybinding troubleshooting output with the extension's handling of the Equal key. Done means == invokes fix-indentation again for the current line in supported language files.
