StoragePath.Normalize unexpectedly adds a "/" at the begining of the path

[fubar-coder]

Around 8 months ago, the option for StoragePath.Normalize changed from includeTrailingRoot to removeTrailingSlash, which is a breaking change, because the path returned by the Blob class is suddenly returned with a / at the beginning.

I can work around this change, but it was unexpected.

I report this issue for the following reasons:

• Missing documentation of a breaking change
• Normalize removes/adds the preceding slash, not the trailing one
