Invoke-Command -Session $s -Command {$PSVersionTable} Fails Due to SemanticVersion

Steps to reproduce

1. Install PowerShell 6.0.0-alpha.8
2. Register its remoting endpoint
3. Create a session to that endpoint and run Invoke-Command -Session $s -Command {$PSVersionTable}

This is another aspect of #1589 that was not fixed when addressing the original issue. The repro also shows that it works through Enter-PSSession, but not Invoke-Command.

This issue appears to be limited to the serialization & deserialization of SemanticVersion during Invoke-Command calls.

Expected behavior

The value of $PSVersionTable should be returned.

Actual behavior

PS F:\GitRepos\PowerShell> $sxs = nsn . -ConfigurationName powershell.6.0.0-alpha.8
PS F:\GitRepos\PowerShell> Invoke-Command -Session $sxs -Command {1+1}
2
PS F:\GitRepos\PowerShell> Invoke-Command -Session $sxs -Command {$psversiontable}

@iSazonov I don’t think we can repro this on a single machine test, it needs to be across machines that have different representations of the same type. @JamesWTruher is working on bring up cross platform and cross PS version tests, this should catch it there.

[iSazonov]

We still haven’t tests for serializer as mentioned above. I believe it is blocking issue. Also we merged #5037 to get SemVer 2.0 - should it be added to PS 5.1 too?
