Component used: WorkManager
Version used: 1.0.0-alpha12

After upgrading to alpha12, all of my Workers written in Kotlin (and CoroutineWorkers, FWIW), complain about the 'Result' return value with an error that says: "One type argument expected for class Result<out T>"

It appears that the Kotlin standard library contains a public inline Result class already: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-result/index.html

The Kotlin Result class is automatically available in every file, so Android Studio (3.2.1) doesn't offer to import the androidx.work.Result class, causing the error since it assumes you want to use the already available kotlin Result.

There were two workarounds, neither very friendly:
1) Use the fully qualified androidx.work.Result
2) Manually adding the androidx.work.Result import statement

Note that:
- Using the fully qualified name, then using the Android Studio option to add import did not work
- Removing the doWork method entirely and using Android Studio's quick fix to implement the method did add an import to androidx.work.Result, so new classes would avoid running into this issue.
