Create parent directory if creating a new file fails (#2978)

With this PR, my encrypted-storage Android PR now works, at least I
couldn't find any further bugs.

Without it, configuring fails with: `Failed to create blob
icon-saved-messages-1803424689.png in
/data/user/0/com.b44t.messenger.beta/files/accounts/0e402b37dcd14a9586aea46294c908f2/dc.db-blobs:
No such file or directory (os error 2)`.
