Do not wrap internal errors in Resolve-MSBuild

[Roman Kuzmin]

A Resolve-MSBuild error was reported: "Collection was modified; enumeration operation may not execute."
From the log, it is not clear where it is in Resolve-MSBuild.

Known details:

• Resolve-MSBuild is used indirectly as use * MSBuild (legacy way)
• It happens in Build-Parallel scenario (relevant?)
• It is not always reproduced

For now, do not catch and wrap internal errors, to see location in logs.
For known user errors, explicitly use Write-Error.

Recommend using Resolve-MSBuild directly: Set-Alias MSBuild (Resolve-MSBuild *)
(at least to reduce the number of moving parts, use adds another layer of complexity)
