TypeError in bs-0.19

Describe the bug
Postprocessing fails with:

The yml file that lead to this error can be found here.

To Reproduce
Steps to reproduce the behavior:

1. Use the linked yml file with buildstock-0.19
2. Do a normal run. I've been getting 50-60 buildings in buildstock.csv, so perhaps n_datapoints could be reduced a little. postprocessing.out is where the error shows up.

Platform (please complete the following information):

• Simulation platform: Eagle
• BuildStockBatch version, branch, or sha: buildstock-0.19
• resstock or comstock repo version, branch, or sha: resstock develop
• Local Desktop OS: Mac

Additional context
I'm testing in preparation for a larger run, with the same down-selection.

@vtnate Can you attach buildstockbatch_crash_details.log here?

[vtnate]

@rajeee I've uploaded the crash details file on my branch.

I also see that this appears to be a duplicate of the issue @lixiliu raised: #199, which tells me the immediate solution is for me to change my upgrades. I'm good in the short term regarding this. @nmerket

[rajeee]

@vtnate Thanks. Yeah, it's failing because there are no time series files for the current upgrade. Though the error could be made a bit more descriptive and we should definitely allow for some upgrades not having any timeseries result.

[vtnate]

Thanks @rajeee, it would be great if upgrades that weren't applicable could still be added to the yml and just resulted in empty timeseries for that upgrade.
