fix auto rotate

I faced 2 problems getting the images rotated correctly when directly uploaded by my iphone (reported from other phones like android too).

1. The method call defined in `imagine.xml` on the `liip_imagine` alias did not work. When compiling the DI there were no added method call.
2. The picture form my iphone hat the orientation saved under the key `ifd0.Orientatio` and not as hardcoded under `exif.Orientation`

With the provided solution my directly uploaded pictures get autorotated correctly.
The if is for old version of imagine bundle. but no idea if the else part is working as it should.
