Fix Azure path comparison when filePath is root ("/")

[tzuan16]

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.
