JMService crashed and generated a core dump during operations.

The JMService stack trace had this:

#0 0x00007fcc359b24f3 in std::_Rb_tree_increment(std::_Rb_tree_node_base const*) () from /lib64/libstdc++.so.6

Expected result: Outage information is corrected so that outages do not overlap. JMService remains operational.

The issue can be reproduced at will with the following steps:

1. Enabled 'fixOutageOverlaps' configuration rule.
2. Create and restore an outage.
3. Create another outage on the same device with back-dated start time between start and restoration time of the first outage.
4. Restore the second outage.
