Fix: Applying blur does not apply pending rotations.

[rovertrack]

Description (required)

context: #6920 (review)

What changes did you make and why?

• applypendingrotation required file to be passed but inside the method it just needed the imageUri to be converted to file object so moved that logic to function itself as the imageUri is global it will be available for all to use.
• added a method call to applypendingrotation after the image blur happens, this saves us from calculating and remapping the entire post blurred image to compare at runtime, as after blur rotating results in the same file.
