fix(firebase_storage_web): fix Error: Unexpected null value. when metadata.timeCreated or metadata.updated

[nilsreichardt]

Description

I had the issue when uploading a file and accessing taskSnapshot.metadata that a Error: Unexpected null value. was thrown. With a bit debugging I found out that at the beginning of the upload the metadata.timeCreated and (or? I'm not sure) metadata.updated are null. Because of the ! the was Error: Unexpected null value. thrown.

Hey 👋
Thanks, effectively according to documentation it can be null.

[nilsreichardt]

Yes I know that it can be null and this is also documented in FlutterFire. But it's impossible to check if it's null. Even taskSnapshot.metadata == null throws the exception because metadata is accessed and inside of metadata is the error thrown.
