When using a query parameter without a scheme, the scheme defaults to `file`. This results in the files in the explorer being technically different from the file picker files because they are file:// instead of vscode-remote://, causing the same file to open twice and causing numerous issues. Normally the file explorer wouldn't even load at all in this case but we provide a file service for file:// URLs as a failsafe for certain files that wouldn't load correctly in the past. These files load fine now using the vscode-remote scheme, so I'm also removing that service. Related: #1351. Fixes #1294.
