Fix runAndroid command

[SandroMachado]

The runAndroid command in the version 0.41 of the React Native has several issues. This PR fixes them.

With 0.41 the --configuration flag was removed from the runAndroid command. It was removed probably due to a bad rebase here. More information can be found in this PR.

Specifying the device id, with the flag --deviceId also bypass all the other configurations. For instance, if a flavor/variant is specified with the flags --flavor or --variant and a device id is also included with the flag --deviceId the flavor/variant is completely ignored.

I also included minor tweaks like always assemble the apkand only install it in a separated step.

With this PR, a command like react-native run-android --configuration release will generate an android apk with the release configuration, like in the version 0.40 of React Native.

I think #12698 deals with this by updating the documentation

Is this going to get merged soon? I'm talking about the fact that --variant will get ignored if you specify --deviceId.
