Giles Van Gruisen 5f1408858a Support additional dependency declaration format
Summary:
Thanks for submitting a PR! Please read these instructions carefully:

- [x] Explain the **motivation** for making this change.
- [x] Provide a **test plan** demonstrating that the code is solid.
- [x] Match the **code formatting** of the rest of the codebase.
- [x] Target the `master` branch, NOT a "stable" branch.

Previously, `isInstalled` was somewhat naively checking for the presence
of a string in the `build.gradle` file to determine whether or not that
dependency was already linked. I.e.:

```
    compile project(':${name}')\n
```

…where `name` is replaced with the name of the dependency being checked.

This was inflexible as it only supported that particular format of
`compile` definition. Another, valid `compile` definition follows:

```
    compile(project(':example') { … }
```

However, this failed the check because it didn't _exactly_ match the
format for which the check was searching the `build.gradle` contents. As
a result, running `react-native link` would incorrectly duplicate the
dependency definition and thus cause a crash upon launching the app.

This change adds an `installPattern` to the object returned from
`makeBuildPatch`, which includes the particular dependency name and is
valid for both `compile` definition formats.

This commit adds an additional compile definition in the associated fixture,
an additional test case in `isInstalled.spec.js` to check for this additional
format, and an additional test in `makeBuildPatch.spec.js` to ensure the
object returned includes the aforementioned `installPattern` Regex pattern.

Sign the [CLA][2], if you haven't already. 

Small pull requests are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it. 

Make sure all **tests pass** on both [Travis][3] and [Circle CI][4]. PRs that break tests are unlikely to be merged.
