jschoubben 9ff47f6aaa Mint an assignment's account once, whoever finds it missing first (issue 1945, ADR 0543, review)
The assign act and the assignments' watch both checked whether an account was
minted and then minted it, and minting overwrites the hash: interleaved, the
bus kept one caller's hash and the node was sealed the other's password, the
crash loop this branch fixes. Both now mint through one statement that inserts
the row only when none stands; the caller whose insert wins seals, the other
seals nothing. issueMissingProcessAccounts mints the same way.

A watch opened again after one ended handed the standing assignments as the
start's look, so one that came to stand in the gap got no bus composition or
grant when its account already stood: only the process's first watch is the
start's look now. The start's look reads the catalogue once and ends with one
composition of the bus's node and the grants; a controller not holding the
lease is told so and tries again rather than dropping the key.

Tests folded to stay within the budget: the assignment tests are three table
tests, the process account and mayIssue tests folded into one of them, and
the concurrent mint is a case of the inventory's rotation test.
Research 072: the grants piece (memberships and credentials heard from placement).
