Error always received on startup

[harleyg321]

Describe the bug
Every time I turn on my raspberry pi, I get a "Can't retrieve printer status" error before it goes into standby.

Expected behavior
Errors shouldn't be shown on startup while we are still waiting for OctoPrint to launch.

General Information:

• OctoDash v1.4.1
• OctoPrint v1.4.0
• Klipper v0.8.0

Additional context
I think what is happening is OctoDash starts before OctoPrint has finished starting, so it is unable to contact OctoPrint, and displays an error. OctoPrint then starts up, at which point OctoDash is able to get the printer status and see that the serial connection has not been opened yet and goes into standby, but not before an error has already been shown (which persists onto the standby screen).
