fix(Timeseries): Temporal x axis defensive check for missing data

[msyavuz]

SUMMARY

There is an intermittent issue with temporal x-axis that causes charts to display NaN or epoch time instead of correct formats. There is a possible diversion from the happy path where coltype got from backend is corrupted that can cause this. This pr aims to fix that by having defensive checks in frontend to display correct formats.
