There seems to be an issue with unencoded filenames when uploading a new
file to the vault.
E.g. file name
"YYbfUTn6ViuRkXzeXXYAAu8z6DwFMrTNtPY3zpjn24RIUmzqqi4=.c9r" will result
in a broken upload. Encoding the filename will solve this:
"YYbfUTn6ViuRkXzeXXYAAu8z6DwFMrTNtPY3zpjn24RIUmzqqi4%3D.c9r"
However, this will actually result in the file's name being encoded. If
the filename and the encoded filename do not match we need to rename the
uploaded file using the correct filename.
