server: remove startup message ERROR:root:initializing

[da-h]

Description

Removing the startup message ERROR:root:initializing.

Motivation and Context

In #842, I've mistakenly left a debug-message in the PR. This should be removed as some users think rightly that this should not show up if everything is ok.

How Has This Been Tested?

Just running visdom now yields:

Checking for scripts.
It's Alive!
INFO:root:Application Started
INFO:root:Working directory: /home/dave/.visdom
You can navigate to http://localhost:8097

Previously, it said:

Checking for scripts.
It's Alive!
ERROR:root:initializing
INFO:root:Application Started
INFO:root:Working directory: /home/dave/.visdom
You can navigate to http://localhost:8097
