Wrong time splitting format

https://github.com/SLNE-Development/surf-api/blob/c5500744592df032c7e6836fbbf0dd8f68653c4c/surf-api-core/surf-api-core-api/src/main/kotlin/dev/slne/surf/surfapi/core/api/messages/CommonComponents.kt#L472

The time formatter always shows the seperator at the beginning, even if there is no previous for example minute when there is only seconds left.
