feat(xo-web/licenses): rebind license to this XOA

[pdonias]

See xoa#55
Requires xoa#58

When an XOA license is bound to another XOA, allow the user to move it to the
current XOA (thus unbinding it from the other one).

Process

1. create a PR as soon as possible
2. mark it as WiP: (Work in Progress) if not ready to be merged
3. when you want a review, add a reviewer (and only one)
4. if necessary, update your PR, and re- add a reviewer

From the Four Agreements:

1. Be impeccable with your word.
2. Don't take anything personally.
3. Don't make assumptions.
4. Always do your best.
