fix (explore): handle null value in date filter

[graceguo-supercat]

SUMMARY

when Date Filter got null in props, explore view page crash and throw JS error like:

TypeError: Cannot read property 'indexOf' of null

TEST PLAN

CI and manual test

[ktmud]

I think the convention is to style the PR title like fix(explore): handle null value in date filter
