LSP broken error infinite loop in Kate when python-language-server not installed

[Alex DeLorenzo]

After enabling the LSP Client plugin in Kate and editing a Python script, I encounter this error:

    LSP Client: Server terminated unexpectedly: python3 -m pyls --check-parent-process

This error message will keep appearing after closed, in an infinite loop.

The error goes away upon installing python-language-server and restarting Kate:
    pip3 install python-language-server

This is a duplicate of this bug from the KDE bug tracker[1], and this issue was fixed with a commit here[2] to Kate's source code back in January.
