Description of problem:
When you receive an e-mail from CFME appliance that your VM provision request was not auto-approved, the subject of the e-mail looks like this:
"Request ID 1 - Virtual Machine Request from  Pending Approval."
There's obviously a word missing after "from".

Version-Release number of selected component (if applicable):
5.10.0.14

How reproducible:
100 %

Steps to Reproduce:
1. Have a CFME appliance with RHV as an infra provider.
2. Setup your appliance in a way that it will send you e-mails about VM provisioning requests.
3. Create a VM provision request that will *not* get auto-approved. For example you can auto-approve requests with VM count == 1, but not auto-approve any VM count above that.
4. Check the e-mails that are received by an approver.

Actual results:
An approver get an e-mail that has this subject:
"Request ID 1 - Virtual Machine Request from  Pending Approval."
Also, body of that mail says:
"Approver,


A Virtual Machine Request received from  is Pending."

As yo can see, there are two blank spaces after the work "from". In body as well as in subject. Also logic of the sentence implies that there's an information missing.

Additional info:
- Logs from CFME appliance are attached.
- I have not altered the original settings of automation domains.
- As far as I know, body of this e-mail is based on Automation domain ManageIQ -> System -> Notification -> Email -> InfrastructureMiqProvisionRequestApproverPending. But I might be mistaken there.
Anyway, if you inspect it, you can see that in the black space, ${/#miq_request.requester.email} should be displayed, but it is not.
