fix(#226): android test failure on RecoverWalletScreenGrabsTest (#130)

Move SCREENGRAB_PAPERKEY build config to debug build type

The `SCREENGRAB_PAPERKEY` build configuration field, used for screengrab tests, was previously defined in both the `debug` and `screengrab` build types.

This commit moves the definition solely to the `debug` build type, as the `screengrab` build type inherits from `debug` and thus already has access to this field.

Additionally, unused imports were removed from `BrainwalletScreengrabApp.kt`.
