What happened?

I upgraded from 9.3.1 to 9.15.0, and I started to see the error Unable to fetch Percy project token. However, from the product map, Percy is disabled.

This PR seems related to the problem where it outputs an error without accounting for the Percy feature to be enabled or not.

What is your expected behavior?

`@wdio/browserstack-service should not output error for services I do not use or is disabled

How to reproduce the bug.

1. Upgrade to 9.15.0
2. Launch a test from my machine to BrowserStack
3. Observe the log
4. The error is output for @wdio/browserstack-service
