Update fax_retry.lua (#4756) 

Setting ignore_early_media=true has a better chance of success for T38 fax transmissions. 

Setting this as a fax variable in default settings is enough for most cases where a successful transmission occurs on the first attempt. However if fax retries are needed this variable was ignored until now.

This change ensures that IF the user sets ignore_early_media=true as a default fax setting it will also be used for fax retry scenarios when T38 is enabled. If ignore_early_media is not set to true then the changes here are ignored thus minimizing risk.
