Windows Terminal installed to Windows Explorer context menu.

It only gave me options for the normal build along with erroring

Apparently I had an empty object in my profile list causing the error. It still doesn't link to Preview when creating menu objects though.

Line 459 in 8c45921

$executable = "$Env:LOCALAPPDATA\Microsoft\WindowsApps\wt.exe"

This should refer to Microsoft.WindowsTerminal(Preview)_8wekyb3d8bbwe\wt.exe instead, depending on $PreRelease or not.

More investigation is needed before this item can be worked on,

1. Cannot find Microsoft.WindowsTerminal(Preview)_8wekyb3d8bbwe\wt.exe on my machine. It seems to be $Env:LOCALAPPDATA\Microsoft\WindowsApps\Microsoft.WindowsTerminalPreview_8wekyb3d8bbwe\wt.exe.
2. On my machine $Env:LOCALAPPDATA\Microsoft\WindowsApps\wt.exe is associated with the preview version. So it seems that this shortcut is not a reliable one and should be changed anyway.

Once investigation is done, we might ship a new version.
