Only convert lore lines that actually look legacy

Browse Source 
Spigot stored previous componenents as new ChatComponentText("legacy codes") which
this patch aimed to convert to the new format.

However, the impl ended up converting all lines.

If a plugin had a section symbol in the lore that isn't a color conversion, it would
make trigger this process every single time.

So now we will only process it if the pattern looks like the legacy bukkit format

Fixes #3869
