Fix Debug build when Azure Presigned and Curl managers are disabled
Should solve issue /relate #251
Tested only manually, not sure if different configurations are supposed to be tested anywhere automatically.
Additional note:
Purpose of DISABLE_DMS_IOMANAGER
is unclear. DMS_IOMANAGER was removed in commit f6ff2cbb, but the option stayed.
At the moment it disables just IOManagerDmsFactory.cpp.
In theory it could also disable whole DmsIoManagerFactory tree, but that might be too big change for the users. So nothing is done with that.
