Consider reordering baseEvents when using EventManager

[embano1]

The current vSphere API used (also against the vcsim tests) is leveraging the EventManager implementation which sends (chained) events in reverse order, i.e. event key is monotonically descending instead of ascending.

Line 87 in 6826a54

for _, be := range baseEvents {

This can be undesirable due to the end user expecting the event keys arriving in (ascending) order.
