shareViaWhatsapp() shares .wai file instead of .jpg.

Hi, Eddy

First of all, I love your plugin and thanks for the hardwork!

I had an issue when using shareViaWhatsapp() with a JPEG image on IOS devices. the image files was shared as a generic file (i.e. whatsAppTmp.wai) instead of a standard JPEG image. The '.wai' file can be downloaded and it is a correct JEPG image once I have renamed the file suffix rto '.jpg' .

I had verified the Whatsapp Docs. It looks like that the URI string and file format ( as *.wai ) are correct.
The same call works correctly on Android devices but not iOS.

Could you shed some light ?

Thanks and have a good day!

Samson
