Fix testCollectorEndpoint typo and add tag assertions in jaeger_test

[IrisTuntun]

1. Fixed the typo testCollectorEnpoint to testCollectorEndpoint.
2. Added assertions on process tags in gen.Batch that was exported in TestNewExporterPipelineWithOptions.

Fixes #1699
Note: gen.Batch has already been recorded in testCollectorEndpoint thanks to #1693
