ideavim-sneak doesn't use mappings from .ideavimrc

[AlexPl292]

It's not possible to define mapping to f for the ideavim-sneak inside of .ideavimrc.
This happens because the extension ideavim-sneak is always loaded after .ideavimrc execution and overrides my f mapping. Also, it sets mapping to s even I defined a different one.
The common vim approach to that is to set the mapping only in case there are no other mappings to the target combination, so instead of map a b they use if hasnomap('b') { map a b }. This approach is also possible with IdeaVim, but you need to bump IdeaVim version to be able to use com.maddyhome.idea.vim.extension.VimExtensionFacade#putKeyMappingIfMissing instead of VimExtensionFacade.putKeyMapping.
