Re·order remakes to (again) fix restarts

In cases where `$(BUILDDIR)/dependencies` exists but
`$(BUILDDIR)/.update-types` (initially) does not, it is important to
check for dependency updates *first*, prior to checking for parser
updates. This is because when parsers are updated, the dependency file
will be deleted, causing the dependency reload recipe to activate
immediately (prior to a restart) if it hasn’t already been checked.

Having correct behaviour depend on the ordering of these recipes isn’t
ideal, but the alternative is checking whether
`$(BUILDDIR)/.update-types` was created *in the course of processing
the make·file* and disabling dependency creation until the next restart
if it had been. This sounds unbearably complex and difficult to phrase
in a readable manner.
