prevent django_manage.py from tracking changes in node_modules

[stebunovd]

The patch prevents manage.py console in PyCharm from being painfully slow when there is a node_modules somewhere in the project tree.

Timings from my current project, running migrate command from manage.py console in PyCharm:

• with the patch: 7 sec
• without the patch: 5 min 19 sec

Developers are not supposed to manually change the contents of node_modules, so I guess it's fine to exclude it from tracking. I also think it is ok to just hardcode node_modules in the method code, because it is hardcoded in Node and developers cannot rename it.

Hello. Since 2018.1 PyCharm does not track all folders, but filters them by pattern instead: https://youtrack.jetbrains.com/issue/PY-27260 Please check if this issue is still actual in 2018.1

Hi there,

PyCharm 2018.1 is indeed faster, it demonstrates 3-4x speed improvement without the patch. However, it is still slow. Here are measurements from my project with PyCharm 2018.1, running migrate without any active migrations to apply:

• with the patch: 5 sec
• without the patch: 1 min 13 sec - 1 min 35 sec (best and worst results)

Of course, 1+ minute is much better than 5+ minutes, but the delay is still very noticeable and annoying.
