Fix bad nesting count when remote calls fail.

The nesting count for services depends on callbacks decrementing
ServiceRecord.executeNesting in response to remote service calls. If a
remote call fails the callback does not get made and the nesting count
gets out of sync. This causes orphans in the executingServices set.

This fix makes the callback locally when the remote call fails.

TransactionTooLargeExceptions caused by Intents containing large
amounts of data were being caught and not propagated to the calling
methods.

This fix propagates TransactionTooLargeExceptions back to the calling
methods.

Fixes bug 19698308.
