TestCase for msiexec /a failing to create correct directory structure

Wine msiexec /a should create an administrative installation and maintain the
source folder structure, same as MS msiexec /a.

But it does not do the latter in cases where the DefaultDir in the MSI
Directory Table contains ".:". Instead, Wine msiexec /a creates a flattened
structure.

Attached is a simple test case .msi, which copies one text file during install.

To test the case, store the StructTest.msi file, and on the Wine CLI, execute
e.g. 
msiexec /a "R:\StructTest.msi" TARGETDIR="R:\StructTest_admin_wine" /qn /L*VX
"R:\StructTest_admin_wine-Log.txt"

Note: Nothing will be installed, only a administrative installation folder
structure is being created.

The attached test file contains
- the StructTest.msi
- the CLI command used
- logfiles for the file trees created by Windows 10 and CrossOver25/Wine 10.0
- logfiles from msiexec for Windows 10 and CrossOver 25/Wine 10.0
- logfile from CrossOver 25/Wine 10.0 with Channels +msi,+msidb

meaning of ".:" for DefaultDirectories
