Roman Khimov 70aed34d77 interop/contract: fix state rollbacks for nested contexts
Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of

    entry
    A.someMethodFromEntry()   # this one has a TRY
    A.internalMethodViaCALL() # this one doesn't
    B.someMethod()

we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.

Fixes #3045.
