_is_relevant_relation missing from import

[Benaiah2320]

While making initial migrations ran into the below error, caused by

File "C:\Users\USERNAME\Envs\PROJECTNAME\lib\site-packages\sql_server\pyodbc\schema.py", line 406, in _alter_field
    if _is_relevant_relation(rel, new_field) and rel.field.db_constraint:
NameError: name '_is_relevant_relation' is not defined

I looked into the file and it looks like it was just missing the import. I added it and the migration completed.

If you want I can put in a pull request, but I thought that was a little much for adding an import statement.

Here is the rest of the error log:
