Robust display of NotConvertibleTypeField errors (fix #3008, #2995)
Since the nametab isn't aware of everything needed to print mismatched
types (cf the bug test-cases), we create a robust term printer that
known how to print a fully-qualified name when [shortest_qualid_of_global]
has failed. These Printer.safe_pr_constr and alii are meant to never fail
(at worse they display "??", for instance when the env isn't rich enough).
Moreover, the environnement may have changed between the raise
of NotConvertibleTypeField and its display, so we store the original
env in the exception.
