PictureChooser: Invalid save location

[andyci]

https://github.com/MvvmCross/MvvmCross-Plugins/blob/master/PictureChooser/MvvmCross.Plugins.PictureChooser.Droid/MvxPictureChooserTask.cs#L88 assumes that the device has external storage which is not always the case. Need to check for this and use internal storage if there is no external storage.

Relevant error message:

Message:

No such file or directory

Stack Trace:

Are any progress about it?
It seems fixing is really straightforward, maybe there is something particular reason not to do it otherwise I think I can make pull request. What do you think about?
