MONGO sink is inserting without use config for create collection like expiration_date

[AlvaroVega]

Since mongo is able to insert even if collection does not exist (then mongo creates it) create collecction methods of mongo sinks where expiration date and others are especified are not applying.

Mongo sink:

STH sink

	// try insert without create database and collection before
	backend.insertContextDataAggregated(dbName, collectionName, lastRecvTimeTs,

Since cygnus 2.10:
[cygnus-ngsi][MongoSink][STHSink] Try to not create database and collection in each insertion (#2019, #1975)

My first approach to fix this issue would be delete first try-catch block

fiware-cygnus/cygnus-ngsi/src/main/java/com/telefonica/iot/cygnus/sinks/NGSIMongoSink.java

Lines 287 to 290 in bb2b344

	try {
	// try insert without create database and collection before
	backend.insertContextDataRaw(dbName, collectionName, aggregation);
	} catch (Exception e1) {

Since list collection introduces the same load which try create collection each time.
