Remove branch name from push

[dontlaugh]

It is possible to specify an alternative default initial branch for git
repositories. This is globally configurable with init.defaultBranch.
See man git-init for details.

We should be able to rely on pushing and pulling from the default
branch without explicitly setting "master", or anything else. dstask
will simply push and pull from the remote named "origin" using whatever
default tracking branch is set.

I think I'll need to rebase after #133 is merged. I see this when running tests:

❯ make test
go test -v -mod=vendor ./...
go: inconsistent vendoring in /home/coleman/Code/dstask:
	golang.org/x/[email protected]: is explicitly required in go.mod, but vendor/modules.txt indicates golang.org/x/[email protected]

run 'go mod vendor' to sync, or use -mod=mod or -mod=readonly to ignore the vendor directory
make: *** [Makefile:17: test] Error 1

do i get this right?

• nowhere in dstask do we refer to the main branch explicitly by name
• as a user of dstask, do you not configure the name of your main branch in any dstask related env var, or dstask config file
• the only place that needs configuration is the git repo itself, which, once setup properly, is sufficient to support the above 2

if so, sounds neat.

That's correct. It's an internal git setting for repos initialized locally, or it's determined by your github or gitlab configuration.
