import-checker: reset context to verify convention in function scope
I got the following error by rewriting hgweb/webcommands.py to use
absolute_import. It is false-positive because the import line appears in
"help" function:
hgweb/webcommands.py:1297: higher-level import should come first: mercurial
This patch makes the import checker aware of the function scope and apply
rules recursively.
