chore(noise): minor refactor of default checks of keypairs (#1104)
* chore(noise): readable default checks for keypairs * chore(noise): fix naming of arg in exists proc * chore(noise): fix naming to make it clearer * chore(noise): inline and remove result usage * chore(noise): move the isDefault function up, replace defaultyVar with value * chore(noise): inline style * chore(noise): static the default check, remove inline pragma
