Try to fix ronmamo/reflections#253

[ziqin]

This PR tries to fix ronmano/reflections#253 by using only the last dot to seperate class name and member name to get a correct name of the synthetic method for lambda expression usage.

Format of the names of synthetic methods for lambda expression body:
lambda$methodNameWhereTheLambdaExprAppears$# where # is a number

The last dot is also the delimiter of class name and member name in the earlier implementation. It was then changed to Math.max(memberKey.lastIndexOf('.'), memberKey.lastIndexOf("$")) but I don't know under what circumstance will the last dollar be a proper delimiter. Please double check my changes.

Test cases are added for both lambda usage and anonymous class usage, as OpenJDK compiler generates different bytecodes for them.

The problem mentioned in #280 about extracting the expected outer method instead of the synthetic one has not been solved in this PR.

some attempt to solve the lambdas problem is fixed and released in aschoerk/reflections8 that merge my PR. At least all cases where we use it my fix works for it:
PR request was merged with this commit (If i'm looking correct) c5efd25
it is said that not all was merged to original reflections. So until this will be fixed we will stay on reflections8 :(
