Should be able to start activity without FQDN format

Given:

I have activities which can be started via activity manager.

When:

I want to start some activity

Expect:

It is sufficient to use its simple name instead of FQDN.

Example:

android.getActivityManagerProvider().getActivityManager().startActivity("io.selendroid.testapp.HomeScreenActivity");

should equal to

android.getActivityManagerProvider().getActivityManager().startActivity("HomeScreenActivity");

In case there are two activities with same simple name, exception has to be thrown.
