Mid Server DOWN due to false "expected service name" error, if the checking script has a PSReadLine/PSConsoleReadLine error

Mid Server DOWN due to false "expected service name" error, if the checking script has a PSReadLine/PSConsoleReadLine error.

The error starts with:
StartupSequencer SEVERE *** ERROR *** The current service named snc_mid_...
Oops, something went wrong. Please report this bug with the details below.
And results in the MID Server going down:
does not match the expected service name snc_mid_.... The current service is being stopped.

This check does correctly get both the service name and wrapper-override.conf name, but the Microsoft error message text is also included in the service name string, and included in the comparison, and shuts the MID Server down unnecessarily.

Unfortunately the known Microsoft bug in PSReadLine module doesn't throw any exception. It just adds the error message to the output.

PSReadline 2.0.0 does not work on PS 5.1 Windows 2012R2 servers

1. Install a MID Server on a windows server host that is subject to the PSReadLine bug. e.g. PowerShell 5.1 on Windows 2012R2 servers, and NET Framework 4.5.2 (the microsoft bug is due to .NET 4.6.1 being expected).
2. Disable the pre-check (to avoid PRB1437409, which is also normal for on-premise customers).
3. Upgrade the MID Server

On startup of the new MID Server, or first startup after upgrading of an existing MID Server, the following is seen in the agent log. Note: this is a false error because you can see the service name does exactly match:

StartupSequencer SEVERE *** ERROR *** The current service named snc_mid_iaasn00076692

Although this is not a problem with Servicenow code, checks may be added to avoid this breaking critical functions.
