[PD] cannot 'upgrade' old patch

[Antoine Rousseau]

Before 0.47, paths declared inside of an abstraction were also propagated
to the caller patch's namespace (and were added on the top of the caller
patch file when saved).

That has been later considered as a bug, thus removed.

So when you save the caller patch with a newer version of Pd, the paths
originally coming from the abstractions declarations are removed from the
file, and objects cannot be created by the caller patch.
The fix is to add the missing [declare]s to the caller patch. Note: these
paths will then be visible from any abstraction (even nested) created by
the caller patch.
