Unhandled exception in autocompletion of invalid command

[opirko-ui]

Hello,
When I write an invalid command in Click REPL - e.g. "nonsensicalcmd" the moment I press space after the command I get this:

Unhandled exception in event loop:

Exception No such command 'nonsensicalcmd'.
Press ENTER to continue...

I would expect that it would write nothing up until the point when I press enter, then I'd expect something like Error: No such command 'nonsensicalcmd'. (Click without REPL writes this). It is definitely odd that there's an unhandled exception.

Used versions:
click 8.1.7
click_repl 0.3.0
Python 3.11.6

Try-catch with a void return here

click-repl/click_repl/_completer.py

Line 277 in 0c32dce

self.parsed_ctx = _resolve_context(args, self.ctx)

seems to resolve the issue. But that's just my naive hotfix. @auvipy ?

you can come with a draft PR with the hotfix and some sort of unit test
