SNOW-1846830 allow triple slash file prefix (file:///)

[sfc-gh-mkubik]

Apparently triple slash prefix doesn't work on windows as it driver resolves it to something like /C:/path/to/file and such path doesn't exist. The primary reason for this is that driver simply cuts file:// prefix from the string provided by user and the result of this operation is directly passed to the upload function. The quick fix is using the java.io.File parsed path.

Without the fix from PR#2035 the upload with file:/// doesn't throw an error but as the test result shows - no file is being uploaded.
