2.9.0: app name shown when trying to share multiple images

[sivaraam]

Summary:
A label ("Upload to Commons") is seen for the Commons app in the share screen near the app's icon when trying to share a single image via external sources (Gallery etc.). When trying to share multiple images, instead of the label the app name is shown. This should be corrected.

Steps to reproduce:

1. Use an external app to select multiple images (more than 1) and share them.
2. See the label near the app's icon

Expected result
The label that appears when trying to share a single image appears near the app's icon.

Actual result
The app name appears near the app's icon.

Device and Android version:
Android 5.1.1 on Samsung Galaxy J1 ace

Commons app version:
2.9.0
