JVM IR: do not attempt to mangle function expressions

For some reasons, lambdas and function expressions are represented
slightly differently in psi2ir. Lambdas are translated to a block with a
function of origin LOCAL_FUNCTION_FOR_LAMBDA and name "<anonymous>", but
function expressions are translated to a block with DEFINED function
"<no name provided>".

Tweak the condition for detecting local functions a bit, to avoid
similar situation in the future if we add some other origins for local
functions.
