Fix "sampling_rate" not updating along with "dt"

[Cloud1e]

I fixed the issue of the attribute "sampling_rate" not updating when "dt" changes.
This happens in resample in resample.py and TimeSeries2Trace in converter.py.
I also edited the test code for the resample and it passed all the cases.

This is great! Thanks for fixing it! I only have two minor comments. We can merge it after you address it. Thank you!

[wangyinz]

The ErrorSeverity should be Complaint instead of Invalid. Also, the algorithm name here is wrong. This is inside resample not TimeSeries2Trace. There are similar issues to the rest of the changes here.

[Cloud1e]

I fixed it and have pushed it.

[wangyinz]

The else branch here is not covered by test. Also, I think we need to add tests for the converter, too. We also need to test for the elog here. I am actually not sure whether elog is correctly retained after the conversion to Trace and back.

[Cloud1e]

I fixed it and pushed it. I think elog is correctly retained during my tests.

btw, I see the python builds failed due to AttributeError: module 'pymongo' has no attribute 'database', which is something we currently have not fixed for the API change of the new pymongo. The commit 8ef0ae3 address the problem by temporarily limit our pymongo to an old version... We might need to look into implementing the changes now...

I fixed this and now it works well.
