Bulk move is not working

[yaras]

I go to issues list, then I select multiple tasks and open context menu in which I select Move and I get:

An Internal Error Has Occurred.
Error: An Internal Error Has Occurred.

After I dug into code I found two issues:

First, move method checks:

• request->params['issue_id']
• request->params['url']['ids']
• request->data['Issue']['ids']

but it does not check request->query['ids'], which should be done as bulk move adds ids query param.

Second, instead of $this->cakeError there should be thrown an exception, for example BadRequestException.

This is already reported in #278.

I also try to fix this issue and open a pull request with my fix proposal.
