fix: export GPX and TCX wrong DeviceName

[muktihari]

• When user changes the deviceName manually (text input), we will try to match deviceName from user's input into our database so we can get a valid manufacturerId and ProductId in case user wants to export to FIT later, however we do not specify a fallback when the mapping value is not found, for GPX and TCX only the deviceName is required.
• This is not related to the issue, but let's just include it: bump xmltokenizer to v0.0.2

Let's do patch release after this 😅
