The bean factory prefix is '&', so we can use a char comparison instead of more heavyweight String.startsWith("&")

I started testing Leyden and Spring AOT on a pretty large Spring Boot application (>1M loc). While the bootstrap was already quite efficient, I get pretty impressive results, going from 13s to about 9s.
At this point, some minor inefficiencies start to show up in profiles, so I propose low effort fixes that result in about 70-100ms improvement.
