No Version Information for some apps

[cstayyab]

I tried to get Details for com.facebook.katana but there is no information about Version. I noticed that following data is missing:

• details => appDetails =>versionString
• details => appDetails =>installationSize
• details => appDetails =>recentChangesHtml
• details => appDetails =>uploadDate
• details => appDetails =>file

All this data exist for almost all the other apps.
