etherlime flatten => TypeError: Cannot read property '0' of null

This fails on all 3 contracts I tried from the argent-contracts repo including simplified examples of having one import or no imports.

@elenadimitrova I found where the issue is coming from and I will do my best to release a fix soon! Thank you.

@elenadimitrova Could you try to install etherlime 2.2.6 and try the flatten command ?

[elenadimitrova]

Yep that works, thanks.
