Proposed changes

Appium allows otherApps to be either a string or an array of strings. When running tests on Browserstack, otherApps has to be passed as an array.

Currently this causes a type error:

wdio.remote({ capabilities: {'appium:otherApps': ["/path/to/app"]} })`

but passing a string with Browserstack results in an error:
