Fix the initial gasmix that is shown in the tank bar of the profile. Also add a meaningful gas name for gases with negative values for percentages. @bstoeger: This is a side effect of the `event_loop` functionality introduced as part of #4198. In the case of an `event_loop("gasmix")` this does not take into account the edge case where there is no gaschange event at the very beginning of the dive, and the first gasmix is implicitly used as the starting gasmix. This happens for planned and manually added dives, but also for some dive computers. We are using the same kind of loop in a number of other places in `core/profile.cpp`, `core/dive.cpp`, `core/gaspressures.cpp`, and `profile-widget/tankitem.cpp`, and I am wondering if we should be converting these to use `gasmix_loop` instead to avoid being bit by this special case?
