Bug 1685187 - [devtools] Fix browser_resources_document_events.js intermittent. r=ochameau.

The test was failing in some case because interactiveEvent and completeEvent had
the same timestamp (which is still valid).
The test is modified to check greater or equal instead of strict greater.
Note that this test still has intermittent around willNavigateEvent and
loadingEvent (see https://searchfox.org/mozilla-central/rev/a2c26b9b49a521f4be39559ca1ca9c345a237c70/devtools/server/actors/webconsole/listeners/document-events.js#11-34)
