This reverts commit 003e34c7.

The resource-to-account relationship is intended to be declared by
predicates (which are used here), but should only be explicitely set on
movements when they *differ* from these rules, as special overrides.
So, setting default accounts on movement is unnecessary work:
- predicate lookup is expensive, and business-model-specific shortcuts may
  be available which such generic implementation cannot implement
- multiplying unneeded relationships increases category table size, which
  is generally detrimental to performances

just test for truth instead of checking in [list of false instance]

fix typos and remove unused variables.

`PasswordTool.analyzePassword` that checks the password is valid for
this reset key.
