Steps to reproduce the bug

As the Image shows, if you open any View containing several StreamInfos, some of them have a bad PrettyTime conversion.

Expected behavior

In German (and other languages), the date is expressed with a certain gramatical case. So if the video was made 2 months ago, the date would have to be translated to "vor 2 Monaten". This suffix only appears with the plural of the word so "1 month ago" would translate to "vor 1 Monat" without the n.

Actual behaviour

The upload date is wrongly declinated in a way that it also receives the case suffix if the unit for the date is singular. "1 month ago" -> "vor 1 Monatn" This actually only happens with part of the dates as seen in the example picture.
