app: Always separate blobs_to_render and last_blobs in ink tool
In ink tool, if last_blobs is empty, the copy of blobs present in last_blobs and blobs_to_render was same. Due to this, when layer boundary is expanded, we move same blobs twice. Due to this a straight line was drawn when starting painting from outside layer boundary. Fixed the issue by storing a duplicate version in blobs_to_render. Updated free part accordingly.
