Fixes #6773.

Description

Call rand_affine_grid() once before call rand_affine_grid.get_transformation_matrix(), since its documented as "Get the most recently applied transformation matrix", or the .affine attribute will not be set.
Also, set randomize=False here since randomization if performed in the beginning of the function.

Please forgive the delay. I've been looking into the code this morning. I think we might want to go a little further than the current PR, but I'll make suggestions in the review once I've come to a conclusion on that.

@function2-llx Ok, I had a look at a limited refactor of RandAffine and the classes that it uses, but I think it isn't possible to make tweaks without making a larger refactor. As such, I think we should go ahead with the change that you are proposing.

Do you want to write some unit tests to cover the change to RandAffine? We certainly need additional tests to cover this.

@atbenmurray Hi, I'd like to help, but I have to rush my conference submission recently (Due on Aug. 15th), so I'm afraid that this PR is the most I can help recently. I can help more after the submission is finished.

@function2-llx Don't worry about it. It has been a very useful spot! I'll write up some additional unit tests to go with it.
