Allow missing EQ or CB results

[AlexAxthelm]

Currently, if either equity or bonds results are missing from the analysis (because the portfolio doesn't include those asset classes) then dashboarding process fails with an error:

cannot open compressed file '/home/workflow-pacta-webapp/create-dashboard183733793/analysis-output/Bonds_results_portfolio.rds', probable reason 'No such file or directory'

This PR allows the process to continue even if one of those files is missing.

Note: tests for EQ- and CB-only portfolios added in 3c443af
