Incorrect execution status for last command run with the PowerShell Extension

[SamErde]

Prerequisites

• [x] I have written a descriptive issue title.
• [x] I have searched all open and closed issues to ensure it has not already been reported.
• [x] I have read the troubleshooting guide.
• [x] I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• [x] I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• [x] If this is a security issue, I have read the security issue reporting guidance.

Summary

The execution status for the last command is being incorrectly reported in the $? automatic variable when using the PowerShell Extension. While using PowerShell in Visual Studio code, the execution status is reported properly by $?.

As an aside, getting the ExecutionStatus via Get-History | Select Id,ExecutionStatus,CommandLine seems to always report 'Completed' even after encountering a "command not recognized" type of error.
