This was causing an issue when calling the `migrate` command in a test case with
the `available_apps` attribute pointing to an application with migrations
disabled using the `MIGRATION_MODULES` setting.
Thanks to Tim Graham for the review.

Debian packages unconditionally byte-compile .py files on installation and
do not silence errors by design. Therefore, we need a way of shipping these
invalid .py files without a .py extension but ensuring that when we
template them, they end up as .py.
We don't special-case .py files so that the all the TemplateCommand
command-line options (eg. extra_files and extensions) still work entirely
as expected and it may even be useful for other formats too.
If SQLITE_MAX_VARIABLE_NUMBER (default = 999) is changed at compile time
to be greater than SQLITE_MAX_COLUMN (default = 2000), which Debian does
by setting the former to 250000, Django raised an exception on queries
containing more than 2000 parameters when DEBUG = True.
