Ignore non-ciphertext files

Basic Info

Affects all versions.

Description

When a file with a valid base32 name exists inside the d directory, Cryptomator tries to decrypt it. For decoded strings > 16 bytes that is not a problem, but if the name is too short to contain the 16-byte IV, Cryptomator throws an exception and doesn't show any directory contents.
