Update lazy_static dependency to "1.0.2"

[Tamschi]

This fixes a bug that can happen in combination with cargo +nightly update -Z minimal-versions on dependent projects.

(I'd like to add this check to my CI script, but it's not a blocking issue otherwise.)

Cause

See rust-lang-nursery/lazy-static.rs#107.

Replication

• Create a new project with a Cargo.toml like this:

  [package]
  name = "dependency-test"
  version = "0.0.0"
  edition = "2018"
  publish = false
  
  [dependencies]
  wasm-bindgen = "0.2.69"

• cargo +nightly update -Z minimal-versions && cargo check

Error

error: cannot find macro `__lazy_static_internal` in this scope
    --> […]\wasm-bindgen-backend-0.2.69\src\codegen.rs:1282:9

     |
     = note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)

Fix

Attached. See also https://github.com/rust-lang-nursery/lazy-static.rs/releases/tag/1.0.2 to confirm this is the correct version.

Thanks!
