Update Tesla to 1.3
This version includes a couple of fixes, adds Gun and Mint adapters and
removes 0.x -> 1.0 config migrator, which for some reason fails under
certain conditions. I had to set override: true
because Quack pins
Tesla to 1.2.0
, but I have looked through the source code and verified
that updating Tesla doesn't break anything there.
Closes #1262 (closed)
