[Revert] This reverts adding foregroundServiceType to many services.

[notandyvee]

After some testing I learned that the foregroundServiceType was unnecessary in many of the services I previously thought required them. This was an oversight. This PR reverts that PR which shouldn't affect any functionality.

To Test:

• ReaderUpdateJobService
  Get’s triggered when you change tabs

• ReaderDiscoverJobService
  When the reader discover tab loads

• ReaderPostJobService
  Service which updates posts with specific tags. Will not happen on discover, but on tabs like subscriptions.

• ReaderSearchJobService
  Happens when searching for blogs/posts in the reader.

• ReaderCommentService
  Loads comment on a post when clicking comments in the reader.

• SuggestionService
  Loads suggestions for autocompletion purposes in the comments section in the reader

• NotificationsProcessingService
  Dismiss or like directly from a notification

• NotificationsUpdateJobService
  Loading recent notifications

• InstallationReferrerJobService
  Service that runs 1 time on clean install in order to track if the app was referred.

• LoginWpcomService
  Login through Wordpress.com.

• SiteCreationService
  Create a site

• WidgetService
  Service used to update the jetpack widget.

• GCMMessageService
  Real-time notifications
