create new AclEntry if ownerEntry is not found

[thurka]

On Windows, GDK Gradle project with object storage fails to start.
There is an error message in the log:

[Error - 4:26:22 PM] Request workspace/executeCommand failed.
  Message: Owner missing, file:C:\Temp\Downloads \vscode-work-datadir \User \workspaceStorage\b372ec8d4119692fb0336080c81661a\ast apache-netbeans-java\userdir\var\cache\nbls.db.connection\db-10622290301022902981.properties
  Code: -32603

Owner missing: error is caused by special Windows setup, where new files do not have owner listed in file permissions. There are some aliases instead.
The situation looks like this:

Find owner JISEDLAC--CZ\jisedlac (User)
 Entry principal BUILTIN\Administrators (Alias)
 Entry principal NT AUTHORITY\SYSTEM (Well-known group)
 Entry principal BUILTIN\Users (Alias)
 Entry principal NT AUTHORITY\Authenticated Users (Well-known group)

none of the entries contains logged user.
This is fixed in this PR by removing all entries and adding new one, with user as principal.
