Fix '--reset' and '--no-load' args combination

[v1k1nghawk]

From a logical point of view, it is not possible to specify '--reset' and '--no-load' arguments at the same time. The current py-tpcc code state allows this, causing the database to be dropped, the new database not being created, and the run phase starting on an non-existent database, resulting in a waterfall of errors. Based on this, it is proposed to introduce a check for the presence of a combination of these two arguments.

Command:

time ./tpcc.py --config mconfig --warehouses 1 --clients 1 --no-load --reset mongodb

Original behavior:
