Update trace location attributes validation

[jurajkusnier]

Update trace location attributes validation according to spec changes:

• Bezeichnung (description) may not be empty, may not contain any line breaks, and may not have more than 100 characters after removing any leading or trailing whitespace
• Ort (address) may not be empty, may not contain any line breaks, and may not have more than 100 characters after removing any leading or trailing whitespace
• Beginn (start) must be before Ende (end) if the type is an event; both must be unset if the type is a location.
• Typische Aufenhaltsdauer (default check-in length) must be greater than zero if the type is a location and must be great than or equal zero if the type is an event (zero meaning no value set)
