Use fsrepo.IsInitialized to test for initialization instead of just testing if the directory exists.

Also add test cases for '--init' option, including one the creates an empty directory.

Closes #3773.

best to put && after the rm, I know it "shouldn't" fail but still.

Sorry. The "&&" are too easy to forget about.

// `IsInitialized` where the quality of the signal can be improved over

Instead of calling twice the req.InvocContex().ConfigRoot why not make under initialize something like

if initialize {
   cfg := req.InvocContext()
   if !fsrepo.IsInitialized(cfg) {
       err := initWithDefaults(os.Stdou, cfg)
// code

This will be problematic with other daemons people have running (port numbers). Not really sure how to solve it.

Yeah... i'm not sure how to fix it either. We should look into adding a way to specify ports from here.

Though not sure if this should block the PR, Its probably a separate concern

It will cause the test to fail on users machines who also have an IPFS daemon running. Should we flag it some how? If so I am not sure how.

We could check if ports from config are bound (8080, 4001, 5001) using netcat and if any of those are, skip the test. How that sounds?

Yeah, lets do that. Its better to print a message about why it fails rather than just randomly failing.

You should be able to use nc -z -w1 localhost 5001

Do you still want to do that? The test won't fail currently.

@kevina Hrm... i think we can probably do without for now. Lets add a todo to add a flag for different ports on the daemon

@whyrusleeping do you think we I should reduce the timeout to 1 sec to minimize the chance of this test failing?

I wouldnt worry about it, lets just make a note to do proper port selection for this later.

Use fsrepo.IsInitialized to test for initialization instead of just
testing if the directory exists.

Also add test cases for '--init' option, including one the creates an
empty directory.
