* test_component: improve valid/invalid event trigger tests
Add test cases for event triggers defined as annotations.
Add additional cases around lambda returning different values.
Improve assertions for invalid tests (each line needs its own `pytest.raises`).
More invalid test cases.
* [REF-3589] raise EventHandlerArgMismatch when event handler args don't match spec
Improve error message for common issue.
Previously when the event handler arguments didn't match the spec, the
traceback resulted in:
```
OSError: could not get source code
```
Now this problem is traceable as a distinct error condition and users are
empowered to debug their code and reference the documentation (to be updated)
for further information.
* raise EventFnArgMismatch when lambda args don't match event trigger spec
Improve error message for another common issue encountered in the reflex framework.
Previous error message was
```
TypeError: index.<locals>.<lambda>() takes 0 positional arguments but 1 was given
```
* Fix up lambda test cases
* call_event_fn: adjust number of args for bound methods
