Tile prefetch creates sometimes invalid png files

Description

As mentioned here: https://github.com/MapWindow/MapWinGIS/issues/117

Sometimes 363 bytes PNG-files are saved, which are invalid.
Because they are saved MapWinGIS sees the files and skips getting new ones.

I created a unit test and sometime GoogleHybrid throws

Most likely this is the place when the invalid PNG-file is created.

I will investigate this more.
