BME680: Minor fix to configuration validation and related log line.

[arcsur]

Description:

This is a minor fix to a voluptuous configuration type check that was set as string but should have been int. This did not stop the code from working but may have caused invalid error messages with a string value that could not be converted properly such as a config typo.

Note that the documentation, already states int correctly.

Something failed in the test case for the travis build but this is not related to my code which passed local tests. It seems to be something related to the Travis build environment missing a component (unrelated to this PR) for the Python 3.5.3 environment only.

I don't know how to request the Travis build to retry without submitting further changes.

Please assist.

Since you have previously reviewed my code....

Could you please help take a look at the Travis build for this. I believe the issue is not with my code but with the Travis build for 3.5.3. The error is it can't find the beer.py custom_component. This appears to be related to your testing setup and not my code.

[MartinHjelmare]

I restarted the Travis build. You can do that yourself by closing and reopening the PR.

@MartinHjelmare Thanks. Will remember that for future.
