improve error message for components

[chriddyp]

These error messages are hard to parse in large projects especially after upgrading. For example, I'm working on a project right now that has the following error message:

  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash_docs/tutorial/__init__.py", line 11, in <module>
    from .import daq_component_examples as daq_examples
  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash_docs/tutorial/daq_component_examples.py", line 969, in <module>
    ''', style=styles.code_container),
  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash_docs/tutorial/utils/component_block.py", line 27, in ComponentBlock
    raise e
  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash_docs/tutorial/utils/component_block.py", line 19, in ComponentBlock
    exec(converted_string, scope)
  File "<string>", line 6, in <module>
  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash/development/base_component.py", line 324, in wrapper
    return func(*args, **kwargs)
  File "<string>", line 66, in __init__
  File "/Users/chriddyp/Repos/dash-stuff/dash-enterprise-docs/vv/lib/python3.6/site-packages/dash/development/base_component.py", line 94, in __init__
    ", ".join(sorted(self._prop_names))
TypeError: Unexpected keyword argument `height`
Allowed arguments: base, className, color, id, label, labelPosition, logarithmic, max, min, scale, showCurrentValue, size, style, units, value

I'm not even sure which component library let alone component is failing!

• I have added entry in the CHANGELOG.md
• If this PR needs a follow-up in dash docs, community thread, I have mentioned the relevant URLS as follow
  • this github #PR number updates the dash docs
  • here is the show and tell thread in plotly dash community

Alright, I added 3 tests and a changelog entry. This is ready for review!

Closing in favor of #1074 which is off the top of dev.
