Fix VSE: Effect strip flickers when moving left handle

The issue was caused by refactoring, see 7afcfe111aacc8bc. Function
`SEQ_transform_fix_single_image_seq_offsets` modified offsets after
handle was moved, but this was not done correctly.

Remove function mentioned above and move strip start when moving left
handle of strips that have only single frame of content by design
(image, text, color, ...).
