Bug fix issue commons-app#1839, changes (commons-app#1845)

* Extracted out PageTitle object's member varaible, displayText in a variable in findTemplate() in MediaDataExtractor
* added null checks for the same varaible [Lets be safe side]
* replaced equals with contains, ie. displayText.contains(title), so that uploads from multiple sources which have different formats still show up coordinates which was not being shown earlier
