Indicator Runner can't find `run_module`
Stacktrace:

```
Traceback (most recent call last):

AttributeError: module 'delphi_quidel_covidtest' has no attribute 'run_module'
```

I've patched this in prod by adding 

```
from .run import run_module
```

to all the indicator `__init__.py` files so that the weekend schedule will be okay, but we should put in a more permanent fix before the next prod release.
