[WIP] [Do not merge] - fix import for livesql

[jrcichra]

This 'fixes' the issue described in #364 for versions using livesql, but breaks CI (not sure why)

For some reason, my Go wants this passed in by value, not with a pointer, even though the vendor function here asks for a pointer:

vendor/github.com/siddontang/go-mysql/replication/binlogsyncer.go:

func NewBinlogSyncer(cfg *BinlogSyncerConfig) *BinlogSyncer {

The CI for this does not pass against Go 1.10: https://travis-ci.com/github/jrcichra/thunder/builds/188509884

But I am able to compile it fine against my fork: https://github.com/jrcichra/thunder which master has additional changes for pulling my fork version.

my program outside of this lib uses go.mod to compile, and includes:

github.com/jrcichra/thunder v0.5.1-0.20201007045717-c82d2fa57e8a

...and go build succeeds with a 1.15.x compiler importing these sections in main of a dependent program:

"github.com/jrcichra/thunder/graphql"
"github.com/jrcichra/thunder/graphql/graphiql"
"github.com/jrcichra/thunder/graphql/introspection"
"github.com/jrcichra/thunder/graphql/schemabuilder"
"github.com/jrcichra/thunder/livesql"
"github.com/jrcichra/thunder/reactive"
