Pause button changes to Play after low-battery notification when a video is playing

Steps to reproduce:

1. Open a video in mediaplayer-app
2. Enable the mock battery:

gdbus call --session --dest "com.canonical.indicator.power" \
             --object-path /com/canonical/indicator/power/Testing \
             --method org.freedesktop.DBus.Properties.Set \
             com.canonical.indicator.power.Testing \
             MockBatteryEnabled \
             "<true>"

3. Trigger the low battery notification:

gdbus call --session --dest "com.canonical.indicator.power" \
             --object-path /com/canonical/indicator/power/Testing \
             --method org.freedesktop.DBus.Properties.Set \
             com.canonical.indicator.power.Testing \
             MockBatteryLevel \
             "<uint32 10>"

4. Dismiss the Low battery notification

Expected result:

Video resumes playing and Pause button is available in bottom left corner

Actual result:

Video resumes playing but Pause button has changed to Play, which is clearly wrong since the video is playing
