Nodemon crashes when dependencies change

[sodic]

Taken from @infomiho's Discord message:

1. When we enable Google auth for instance, we update the deps and start npm install for the server.
2. Nodemon crashes since it restarts before we finish the npm install
3. It stays crashed since it won't restart on changed deps

@Martinsos commented:

Aha hm! And it stays crashed, ok that sucks. I guess those deps are maybe too far above, is that the reason? Because they are in the node_modules that is above the server/? Because it seems to me this was not happening before like this, and this would explain it.

Yeah I don't think we have a good way to easily restart nodemon from outside, I remember I was exploring this in the past already and haven't found a simple/nice solution.

I did add a delay for nodemon, after file changes, that was supposed to ensure other smaller chores before it settle down, but yeah that isn't enough for npm install.

I am sure we could do some stuff, but I don't think it is clean/simple.
