Polymer access to log file broken when using new log file command line

[TD22057]

Description:

If the new command line input for the log file is used from PR #9422, the polymer developer tools info page cannot find the log file location. It uses the default log file location and the hass config path to load a file that is no longer there. This PR fixes that issue by creating a new variable ERROR_LOG_PATH which components/api.py can access to load the actual log file location.

FYI I could not run tox. The current state of the dev branch throws the following error. Manual tests were run w/ the fix and the webui finds the default or custom log file correctly now.

tests/components/cloud/test_auth_api.py:4: in <module>
    from botocore.exceptions import ClientError
E   ImportError: No module named 'botocore'

• Local tests with tox run successfully. Your PR cannot be merged unless tests pass
• New dependencies have been added to the REQUIREMENTS variable ([example][ex-requir]).
• New dependencies are only imported inside functions that use them ([example][ex-import]).
• New dependencies have been added to requirements_all.txt by running script/gen_requirements_all.py.
• New files were added to .coveragerc.

If the code does not interact with devices:

• Local tests with tox run successfully. Your PR cannot be merged unless tests pass
• Tests have been added to verify that the new code works.

Please store data in hass.data, a dictionary for this purpose. We should not use globals.

Tox does not re-create the test environment on each invocation. Since our test requirements changed, you need to re-create it. Run once: tox -r

Fixed. Thanks for the help. I tried to check the key I selected to make sure it wasn't in use somewhere else but that proved to be difficult.
