Missing env TAIGA_SSL_BY_REVERSE_PROXY in Dockerfile

[ArkadiuszZolnik]

When trying to build image got an error:

File "/usr/src/taiga-back/settings/docker.py", line 23, in <module>
    if os.getenv('TAIGA_SSL').lower() == 'true' or os.getenv('TAIGA_SSL_BY_REVERSE_PROXY').lower() == 'true':
AttributeError: 'NoneType' object has no attribute 'lower'

Adding to the Dockerfile
ENV TAIGA_SSL_BY_REVERSE_PROXY False
Solved the problem

The hint above solved the issue in my instance, too.

+1, this should get fixed.
Adding the line to ./Dockerfile worked.
