cmis: allow http authentication even when password is empty

Test environment for CMIS server using Apache Chemistry and by
default it has just username without password for authentication.
But libcmis uses authentication only if both username and password
are given.

Corresponding patch is already applied to libcmis master.

Using default patch level 1 for libcmis patches, updated existing patches.
