fix(autocert): rebuild SNI matcher after ObtainCertAll operations

The ObtainCertAll method was missing a call to rebuildSNIMatcher(),
which could leave the SNI configuration stale after certificate
renewals. Both ObtainCertIfNotExistsAll and ObtainCertAll now
consistently rebuild the SNI matcher after their operations.

This was introduced in 3ad6e98a17,
not a bug fix for previous version
