Upgrade homer-api & homer-ui to 7.x
I saw that
homer-ui has a 7.8.1 release,
community/homer-api are at 5.0.6, however I find no recent Release for
homer-api at https://github.com/sipcapture/homer but the default branch is
homer7 and "HOMER 7.7 (Seven)" is mentioned at the top of the README.
homer-ui shouldn't be upgraded to latest release without also upgrading
homer-api but I won't do it myself right now. I opened this issue to not forget and to inform someone who might want to take this on or comment on it.
