URL: https://github.com/apache/polaris/pull/385

   # Description
   
   The `AzureLocation.isChildOf` method is currently broken if the parent path 
points to the root of the container (e.g. 
`abfss://[email protected]` or 
`abfss://[email protected]/`). The `filePath` of the path in 
this case would be parsed as `/` since we always add a "trailing slash". Now if 
the comparing child path looks something like 
`abfss://[email protected]/some/file/path/metadata`, the 
`filePath` would be parsed as `some/file/path/metadata/` after applying the 
trailing slash, leading to the failure of the 
`childFilePath.startsWith(parentFilePath)` check since the childFilePath 
doesn't start with a slash.
   
   Fix is to always ensure a leading slash on top of ensuring a trailing slash.
