* Bridge create constraints tests.

* Define the door's bridge asset collection as the collection of all
* the issuing assets for which the door account is on the issuing chain
* and all the locking assets for which the door account is on the
* locking chain. (note: a door account can simultaneously be on an
* issuing and locking chain). A new bridge is not a duplicate as long
* as the new bridge asset collection does not contain any duplicate
* currencies (even if the issuers differ).
*
* Create bridges:
*
*| Owner | Locking | Issuing | Comment |
*| a1 | a1 USD/GW | USD/B | |
*| a2 | a2 USD/GW | USD/B | Same locking & issuing assets |
*| | | | |
*| a3 | a3 USD/GW | USD/a4 | |
*| a4 | a4 USD/GW | USD/a4 | Same bridge, different accounts |
*| | | | |
*| B | A USD/GW | USD/B | |
*| B | A EUR/GW | USD/B | Fail: Same issuing asset |
*| | | | |
*| A | A USD/B | USD/C | |
*| A | A USD/B | EUR/B | Fail: Same locking asset |
*| A | A USD/C | EUR/B | Fail: Same locking asset currency |
*| | | | |
*| A | A USD/GW | USD/B | Fail: Same bridge not allowed |
*| A | B USD/GW | USD/A | Fail: "A" has USD already |
*| B | A EUR/GW | USD/B | Fail: |
*
* Note that, now from sidechain's point of view, A is both
* a local locking door and a foreign locking door on different
* bridges. Txns such as commits specify bridge spec, but not the
* local door account. So we test the transactors can figure out
* the correct local door account from bridge spec.
*
* Commit to sidechain door accounts:
* | bridge spec | result
* case 6 | A -> B | B's balance increase
* case 7 | C <- A | A's balance increase
*
* We also test ModifyBridge txns modify correct bridges.
