Description of problem:
trust-fetch-domains does not add idrange for subdomain found

Version-Release number of selected component (if applicable):
ipa-server-3.3.3-8.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. Setup Trust with AD forest root domain
2. Add a new subdomain to the AD forest / delete an existing subdomain with
# ipa trustdomain-del domain.com sub.domain.com

Delete its idrange
# ipa idrange-del SUB.DOMAIN.COM_id_range

3. Run
# ipa trust-fetch-domains

Actual results:
The subdomain is found, but no idrange call is made to add an idrange
automatically for that subdomain

Expected results:
idrange is added for the fetched subdomain
