Gracefully handle spans without logs field

[MaXal]

Searching of spans throws "Cannot read properties of undefined (reading 'some')" exceptions and breaks UI

To reproduce:

1. Open the attached file via Search|Upload: opentelemetry (8).json
2. Type bootstrap in search

The following exception will be thrown and UI will crash completely:

chunk-JFYQRAKV.js?v=ef5bea20:9145 Uncaught TypeError: Cannot read properties of undefined (reading 'some')

[prettier-lint] *** PLEASE RUN yarn prettier AND RESUBMIT ***

also, DCO check is still failing (easiest is to squash commits and resubmit just one as signed)

[yurishkuro]

btw the reason DCO is failing is because it looks like you have different emails in github account and your local git config

[MaXal]

Sorry for the mess, and thank you for your patience; I fixed the email address in the repository to match the one in Github and the prettier warning in the test file.

[yurishkuro]

tip for the future - do not create PRs from the main branch of your fork, always use a new branch

[yurishkuro]

Thanks!
