can't do this while doing that megaticket

[mitchellwrosen]

There's currently a restriction on performing these sequences of actions, which would be nice to lift:

while resolving this	can you delete?	can you update?	can you upgrade?	can you merge?
delete	no	yes	no	no*
update	no	yes	no	no*
upgrade	no	yes	no	no*
merge	no	yes	no	no*

• no* - you shouldn't be able to for the same reasons as the other "no"s, but the current implementation allows it (just an oversight)

(n.b. in the current implementation, "while resolving a delete" is the same as "while resolving an update", so those rows are the same)
