Do not kill an existing daemon, but check if one exists

[IGassmann]

This removes the functionality of killing an existing daemon and instead checks for an existing one and connect to it.

This will also close #298.

This will wait for electron-userland/electron-builder@ad199c4 to be released.

@IGassmann are you sure daemon killing actually happens? Is it default behavior? I'm relatively confident that if I launch lbrynet-daemon from the command line and then launch the app, that it will connect to that running instance already.

[IGassmann]

@kauffj that was the behavior before the refactoring. However, during the refactoring I made the app to kill any existing daemon before starting in order to fix #298. With the coming electron-builder release it won't be necessary anymore.

@IGassmann does electron builder need to be updated again after the latest commit in: electron-userland/electron-builder#2516

[IGassmann]

@tzarebczan Yes, I'm waiting for 20.5.0 to be released for upgrading. It'll also solve this: electron-userland/electron-builder#2670.

Thanks for notifying me.
