Switch to run context by default

[janpio]

Currently coho runs on the install/checkout location parent of coho (!), not where you execute it. For that to happen, you have to actually use the -g/--global option.

As this is super easy to forget, and the run context is much more expected (even with documentation via #237), we should change this in a major version and, if necessary, add an option to not use the global context if you choose so.

IMHO it should target current working directory or an explicitly provided path.

No need for a flag that makes it use it's parent dir.

IMHO it should target current working directory or an explicitly provided path.

Agreed on my part.

Interesting counterpoint by @purplecabbage in [1]:

Remember that coho has very limited use and
is not really intended for wide adoption. It is for developers working
with the collection of cordova repos, and managing the multitude of repos
that we have.

I just labeled PR #237 as a bug and this one as an enhancement.

I hope we get PR #237 merged for the sake of clarity.

#237 was successfully merged and helps developers to understand what is going on.
