httpss issue in email notification

Hi,

I'm re-opening https://github.com/kaltura/platform-install-packages/issues/260 here to send a pull request.

We had been struggling from the following wrong service url in resetting password. As you see, we are using https://HOSTNAME:443 as our service url but the link is becoming "httpss" instead of "https".

```
Hello Shoji Kajita,

A new Kaltura Admin Console user account on Kaltura's online video platform has been created for you by Kaltura Administrator.

Your Kaltura Admin Console Login Information:

Login email: xxxx@kyoto-u.ac.jp.
To set your user password go to:

httpss://HOSTNAME:443/index.php/kmc/kmc/setpasshashkey/NHwxNDE0ODEyNzk1fDk5ZjI2ODMwNWE3MmRhOTg5ZDIwN2Y2MDIyZTJlMzlhMDU3YTQ0OGE=

Please note that these credentials (login email and password) will be used when you open a KMC user account
with the same login email address that you are using for the Admin Console.

Your role in the admin console account is : System Administrator.

Once you have set your password you can log into Kaltura's Admin Console at https://HOSTNAME:443 and get started!

```

This issue occurs when the following setting is used in /opt/kaltura/app/configurations/local.ini
```
[password_reset_links]
default = https://FQDN:443/index.php/kmc/kmc/setpasshashkey/
```

So, the protocol replacement from http to https should be performed when $resetLinkPrefix is NOT https.
