If the advisor has a valid claim on authorship it would be misconduct to do thisremove them as an author. Probably plagiarism. The journal would object if it knows, which it might, due to the earlier submission.
I think you would be wise to work this out with your advisor: who is author, what order, etc. It they decide to let you publish as a sole author you still need to give them an acknowledgement.
Who submits is much less important than the authorship question. That is more an administrative question than one of conduct. The only real issue is keeping some sort of good relations with the advisor (if possible).
