word_boundary doesn't work well in some cases

[ericphanson]

With FuzzyQuery's:

it looks like FuzzyQuery doesn't respect word_boundary? It allows the edits to occur on the leading space

With augment:

julia> word_boundary(augment(Query("hello goodbye")))
ERROR: MethodError: no method matching reconstruct(::KeywordSearch.Or{Tuple{Query, Query}})
Closest candidates are:
  reconstruct(::FuzzyQuery) at /Users/eph/KeywordSearch.jl/src/helpers.jl:34
  reconstruct(::Query) at /Users/eph/KeywordSearch.jl/src/helpers.jl:35
Stacktrace:

   @ REPL[39]:1

julia> augment(word_boundary(Query("hello goodbye")))
Or
├─ Query(" hello goodbye ")
├─ Query("hello goodbye ")
├─ Query(" hellogoodbye ")
├─ Query("hellogoodbye ")
├─ Query(" hello goodbye")
├─ Query("hello goodbye")
├─ Query(" hellogoodbye")
└─ Query("hellogoodbye")

The first case errors, which is annoying, and the 2nd case makes way to many things; we only want to augment the inner space, not the outer ones.
